视频头脉冲在社区糖尿病患者前庭功能筛查中的应用OA北大核心CSTPCD

Objective To report results of video head impulse test(vHIT)vestibular function screening in commu-nity diabetic patients.Methods Diabetic patients(n=32)and control subjects(n=32)in Chaoyang District,Beijing,re-ceived vestibular function assessment using vHIT.Results Significant differences in vHIT gain between the diabetic and control groups were noticed(χ2=10.536,P<0.01).Abnormal saccades occurred in 50%of the diabetic patients,mostly in-volving the horizontal semicircular canal(68.75%),compared to only 9.38%of the subjects in the control group show-ing abnormal saccades,all with horizontal semicircular canal involvement(χ2=14.083,P<0.01).Of the diabetic patients,22(68.75%)had vestibular symptoms and 10(31.25%)did not.vHIT gain showed significant differences for bilateral anterior and right posterior semicircular canals between the two groups(P<0.05),but not for bilateral horizontal and left posterior semicircular canals(P>0.05).Presence of absence of vestibular symptoms had no effects on abnormal saccades(χ2=2.327,P>0.05).Significant differences in vHIT gain were noticed between patients with disease durations≤10 years(n=13)and those with disease durations>10 years(n=19)(P<0.05),with the latter showing more abnormal sac-cades(χ2=6.348,P<0.05).Conclusion vHIT can be used for vestibular function assessment in the community popula-tion.Diabetic patients are prone to vestibular impairment and horizontal semicircular canal involvement is the most com-mon.Prolonged diabetes is associated with increased risks of vestibular function impairment.
